Abstract (en)
[origin: US2022104731A1] A glucose-specific sensor has a glucose limiting layer (GLL), an enzyme layer and an interference layer. The GLL comprises polyurethane with a molecular weight greater than 100,000 Daltons that is physically crosslinked with a water-soluble polymer having a molecular weight greater than 100,000 Daltons. The interference layer has a polymer formed from pyrrole, phenylenediamine (PDA), aminophenol, aniline, or combinations thereof. Methods for making a glucose-specific sensor include mixing a monomer with a solvent to form a monomer solution, applying the monomer solution to a substrate and electropolymerizing the monomer to form a polymer on the substrate. The polymer is an interference layer for the glucose-specific sensor. An enzyme layer is formed on the interference layer, and a glucose limiting layer is formed on the enzyme layer.
